Title: Manufacture of hair-populated material
IPC: A41G3/00
Filed: 1972-03-09
Abstract: 1350315 Hair-pieces T F MOORHEAD 1 Nov 1972 [9 March 1972 18 May 1972] 10925/72 and 23547/72 Heading A4V A method of producing hair-populated material comprises electrically charging a bundle 23 of hairs to cause hairs in the exposed end 25 of the bundle to take up mutually repelled positions, embedding the exposed ends of the hairs in a base layer material 20 which is in a softened or fluid state, and solidifying the base layer material to secure the hairs therein. Means may be provided to limit the repulsion of the hairs. As shown the bundle 23 is pressed into a comb-like surface on the electrode 16 of a Van de Graaff generator. Below the electrode is a hot-plate 17 and a tray 18 having a rim 19 of curved section. A charged ring 22 is supported by threads which form a support 21 and depend from the electrode. The ring may be split and pivoted to enable location around the bundle of hairs. The ring may be bridged by a rod which distributes the hairs to form a hair-free line. The bundle of hairs may be attached to the electrode by adhesive tape or the bundle may carry a wire which is passed through perforations in the electrode. The tray 18 holding base layer material in the form of a liquid plastisol is raised for the hair ends to penetrate the base layer material. The hot-plate is switched on causing the base layer material to partially set. The bundle of hairs is detached from the electrode and the base layer material heated in an oven to complete the setting. The resulting base layer material is flexible and partially transparent. The setting of the base layer material may alternatively be completed by heating in situ with radiant heat. In another form the base layer material is removed from the tray after the partial setting and fastened around a positive casting of the scalp. The base layer material is formed to the contours of the casting and finally set by heating in an oven. In alternative forms the base layer material is initially in the form of fine granules. The base layer material may be a thermoplastic solid which is softened by heat to enable partial or complete penetration by the hair ends. Softening may also be obtained by solvent treatment. The base layer material may be coloured and include fillers to induce microporosity. A reticulate reinforcement may be incorporated. The apertures of the reticulated reinforcement may be completely occluded, or only partially occluded to provide porosity. Natural hairs or synthetic fibres may be used. The base layer material may be given an electrical potential opposite to that of the hair ends. The electric charge may be supplied by a transformer operating off the mains. The means to limit the repulsion of the hairs may take the form of a magnetic or electrical force field.

Escapements.-A post P, Fig. 1, carrying a knife-edge S supports a yoke D, G with bearing- plate C, a rocker A having bearing-saddles f and a bell-crank K which is attached to a saddle k and has a counterpoise Q. The yoke constitutes the head of the pendulum E and has arms F which carry screws H having globular heads. The rocker is loaded by two weights Z and terminates in two flat rings B which receive small weights, Fig. 4, in the form of caps for the screws. Instead of an escape wheel, the arbor O carries a. double vanes R having a notch T and pallet V at each end, and an arm W attached to the rocker is bent to form a counterpallet X. The arm K of the bell-crank bears against an eccentric N on the arbor O, and the arm I forks about a peg d projecting from the rocker. Starting from the position shown, the pendulum, on nearing the limit of its swing to the right will lift the right hand little cap off the rocker so that this tilts under the unbalanced weight of the left-hand cap, and the vane R escapes to make half a revolution. The bellcrank K following the eccentric restores the rocker to the initial position, letting the right hand cap load the pendulum in the return swing till it is left on the rocker again. In a modification, a pin wheel replaces the vane and a wave cam the eccentric.

Title: Production of carbon disulphide-insoluble sulphur
IPC: C01B17/12
Filed: 1953-04-24
Abstract: Sulphur containing a high proportion of the carbon disulphide-insoluble Sm  form is produced by quenching sulphur vapour in a stream of water to a temperature of not more than 90 DEG  C. Preferably, the sulphur vapour is diluted with an inert gas such as nitrogen, carbon dioxide or carbon monoxide, and the quenching water is sprayed into the sulphur vapour by atomizing with inert gas.  A plastic sheet of sulphur free from sulphur dioxide is obtained which is freed from water by intensive rolling.  The sulphur loses its plasticity after storing for some days and may then be ground.  The proportion of Sm  in the product depends on the temperature from which the sulphur vapour is quenched, for example, 69.4 per cent. of Sm  is produced by quenching sulphur vapour at a temperature of 1,100 DEG  C., and 36 per cent. of Sm  at a temperature of 450 DEG C.ALSO:Formation of surface bloom on rubber is prevented by vulcanizing with sulphur containing two parts of Sm  (carbon disulphide-insoluble sulphur) to each part of Slambda.  Such a product may be produced by quenching sulphur vapour in a stream of water to a temperature of not more than 90 DEG C.  The proportion of Sm  in the product depends on the temperature from which the sulphur vapour is quenched.
